PFC Front V3 Slotted Rotor/Hat Assembly - Left - Subaru WRX STI (2004-14), BRZ/GR86 PP
The PFC Front V3 Slotted Rotor/Hat Assembly (Left, #326.053.63) is a direct-fit upgrade for Subaru WRX STI (2004-14) and BRZ/GR86 Performance Package models. Featuring PFC’s patented V3 floating system, high-carbon alloy discs, and slotted design, this two-piece rotor delivers maximum cooling, reduced vibration, and consistent braking lap after lap. The reusable hat design also makes future servicing more cost-effective, allowing you to replace just the rotor ring when worn. Built for track performance but reliable enough for aggressive street use, the V3 assembly brings pro-level stopping power to your Subaru.

The PFC Front V3 Slotted Rotor/Hat Assembly – Left (Part #326.053.63) brings motorsport-grade braking performance to Subaru WRX STI (2004-14) and BRZ/GR86 Performance Package applications. Built as a two-piece floating system, it pairs a precision-machined aluminum hat with a high-carbon alloy rotor ring, joined via PFC’s patented V3 attachment system. Unlike traditional bolted assemblies, the hardware-free V3 connection allows both radial and axial float, dramatically reducing thermal stress, pedal pulsation, and vibration.
The slotted rotor design enhances initial pad bite, continuously refreshes the friction surface, and clears away gases for consistent braking power under repeated heavy use. Internally, precision-turned directional vanes optimize airflow and cooling, keeping brake temps under control even during extended track sessions. Manufactured to exacting tolerances (runout < 0.001", thickness variation < 0.0003"), the V3 system ensures smooth, confidence-inspiring pedal feel.
Designed as a direct-fit replacement for OEM brake hardware, the V3 assembly also offers long-term cost savings: the reusable hat allows future rotor ring replacements without buying a full new assembly. Whether you’re running time attack, track days, or pushing your Subaru hard on backroads, the PFC V3 rotor system delivers unmatched durability, control, and performance.
